[ Going through some old warnings... ]
Hello Sylwester Nawrocki,
This is a semi-automatic email about new static checker warnings.
The patch babde1c243b2: "[media] V4L: Add driver for S3C24XX/S3C64XX
SoC series camera interface" from Aug 22, 2012, leads to the
following Smatch complaint:
drivers/media/platform/s3c-camif/camif-capture.c:463 queue_setup()
warn: variable dereferenced before check 'fmt' (see line 460)
drivers/media/platform/s3c-camif/camif-capture.c
455 if (pfmt) {
456 pix = &pfmt->fmt.pix;
457 fmt = s3c_camif_find_format(vp, &pix->pixelformat, -1);
458 size = (pix->width * pix->height * fmt->depth) / 8;
^^^^^^^^^^
Dereference.
459 } else {
460 size = (frame->f_width * frame->f_height * fmt->depth) / 8;
^^^^^^^^^^
Dereference.
461 }
462
463 if (fmt == NULL)
^^^^^^^^^^^
Check.
464 return -EINVAL;
465 *num_planes = 1;
regards,
dan carpenter
